采用Zr41Ti14Cu12.5Ni10Be22.5块体非晶合金（BMG）制备了直径7.5mm、长7.5mm的轴承滚子。通过大负荷高速真实的旋转试验，评价了轴承滚子的使用寿命，并与商品GCr15钢滚子的使用寿命进行了比较。结果表明，锆基大块非晶合金轴承滚子的耐磨性优于GCr15轴承滚子。这两种轴承滚子的磨损行为不同。
Bearing rollers, 7.5mm in diameter and 7.5mm in length, were prepared from Zr41Ti14Cu12.5Ni10Be22.5bulk metallic glass (BMG). The working life of the bearing rollers was evaluated through a real rotation test with a large-load and at a high-speed, and compared with that of commercial GCr15 steel rollers. The results show that the bearing rollers of Zr-based bulk metallic glass have a better wear resistance than the commercial GCr15 ones. And the wear behaviors are different for these two kinds of bearing rollers.
